Lumber Sanitation: Wood-Rotting Fungi.— X. 
Figs. 1 to 4. — A severe infection of an unidentified fungus in an Alabama lumber yard: 1, Open shed 
where the fungus has progressed upward to the second bin, 5 feet from the ground; 2, corner of closed 
shed on the same premises where rolls of tarred roofing paper resting on the floor (not shown in the 
picture) were severely rotted at the ends; 3, the shed shown in figure 1, showing how the infection 
started by piling too close to the ground over a cinder fill; 4, the same shed after the lower bins had 
been raised in an effort to control the spread of the rot. Figs. 5 and 6. — Peniophora gigantea: 5, Inter- 
mixed with molds and developing on moist pine shingles in a clo 5 e pile in a Tennessee retail yard 
(growth, which an antiseptic dip at the mill would have prevented, had started during transit); 
6, the mature stage growing on a pine log.
